yup, that's the thread with my custom mod. Should be video footage of it in action somewhere on there too. I've had a lot of requests to make them for other people. but it's so much work, and I pretty much need the game to do it. As every piece had to be custom altered to fit exactly. And the wiring up of the moveable arm was a PIA as well. Even for $500, it wouldn't be worth me doing them.
